How often should I clean my K&N air filter?

Cleaning depends on your driving conditions. K&N recommends cleaning when you see a buildup of dirt and debris, or every 50,000 miles under normal highway conditions. Off-road use requires more frequent cleaning.

Do I need to oil the filter after cleaning?

Yes, K&N air filter oil is essential to the filter's performance. The oil helps trap dirt and debris while allowing air to flow freely. Use only genuine K&N filter oil to avoid damaging the cotton fibers.

What is the warranty on this K&N air filter?

This K&N air filter is backed by K&N's Million Mile Limited Warranty. This means K&N warrants that the filter will perform for one million miles, assuming proper cleaning and re-oiling according to K&N's instructions.
